MOTOR FOR OPERATING CHURNS.

SPECIFICATION forming part of Letters Patent No. 401,861, dated April23, 1889.

Application filed November 19, 1888. Serial No. 291,201. (No model.)

To ctZZ whom, it may concern:

Be it known that we, EDWIN NEWTON SHA- FER and JOHN DILLOND KING,citizens of the United States, residing at Kiowa, in the county ofBarbour and State of Kansas, have invented certain new and usefulImprovements in M0- tors for Operating Ohurns; and we do declare thefollowing to be a full, clear, and exact de scription of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in motors for operating churns,and the novelty will be fully understood from the following descriptionand claims, when taken in connection with the annexed drawings, inwhich- Figure 1 is a front view of a machine embodying our improvements.Fig. 2 is a vertical sectional view of the same and Fig. 3 is aninverted plan view of the dasher-shaft gear or pinion, showing thegovernor or regulating device in position.

Referring by letter to the said drawings, A indicates a vertical frame,which is substantially braced and sufficiently high to receive theoperating mechanism and properly support the same. This frame A ispreferably composed of two uprights, a, within which is journaled theshaft of a drum, 13, provided at one end with a suitable crank forturning the same and at the opposite end with a gearwheel, C, forimparting motion to another gear, which willbe presently explained. Theend of the drum-shaft carrying the gear is also provided with a fixedratchet, O, and a pawl, c, is pivoted in a convenient position to engagethe said ratchet and prevent the said drum-shaft from backward movement.The said uprights are connected by a crossbar at their upper ends, asshown at Z), and on this cross'bar is journaled a pulley, over whichpasses a rope, one end of which is secured to the winding-drum and theopposite end to a weight, D, provided with side grooves, (shown indotted lines,) to travel on the uprights a.

While we have shown and described the pulley for the weighted cord asbeing journaled on the crossbar of the uprights, yet it is obvious thatsuch pulley may be journaled to the ceiling of a room or to any otherconvenient object.

E indicates an upright, which is arranged to one side of one of theuprights a, and M. another upright adjacent to the uprights a, and whichtogether form a bearing for the ends of'two horizontal shafts, F and G.

On one end of the lower horizontal shaft, G, is fixed a small gear orpinion, d, which meshes with the large gear O on the drum-shaft andtakes motion therefrom. This shaft G has fixed to it, adjacent to thegear cl, a larger gear, 6, which meshes with a gear, h, fixed on theshaft, F, above. The shaft F carries a fixed gear, I, and a combinedpinion and gearwheel, K L, respectively, loosely mounted on the saidshaft and held in place by an ad'- justable collar, The shaft G hasloosely mounted on it a combined pinion and gearwheel,1' K, and acombined pinion and bevelgear, L R, the two sets of gear being separatedby a collar, L and held in place by a collar, K Motion is transmittedfrom the wheel 0 to the pinion cl and shaft G. The gear 6 on the shaftGr meshes with the pinion h, and thereby gives motion to the shaft F.The gear I on the shaft F meshes with the pinion I, and the gear Kmeshes with the pinion K. The gear L, which moves with the pinion K,meshes with the pinion L, which in turn moves with. the bevel-gear R.Thus it will be seen that the speed is constantly increased from thedrum. B to the gear R.

The main frame is provided with a suitable base, H, and on this base,between the uprights E and one of the uprights a, or the upright M, issecured the churn body or tub N.

Z indicates small angle-irons secured, respectively, to the adjacentsides of the uprights E and M at a point above the churnbody, and aredesigned to receive setscrews or bolts m, whereby the cover of the churnmay be secured in position.

P indicates the churn dasher-shaft, which has a bearing at its lower endin the bottom of the tub or body, and its upper end passing through anaperture in the cover thereof, and is provided with a gear carrying agoverning device. This beveled gear or pinion Q, which is secured to theupper end of the (flasher-shaft, meshes and receives motion from thebeveled gear R, secured to the horizontal shaft G. Fixed on thechurn-cover and surrounding the shaft P is a collar or sleeve, U, abovewhich is the pinion Q.

S indicates two levers pivoted to the under side of the small beveledgear which moves with the dasher-shaft. The outer ends of these leversare adjustably provided with weights T, which may be moved to or fromthe pivotal point and secured by means of a setscrew or the like.

U indicates clamping-shoes, which are also pivoted at one end to theunder side of the gear, as better shown in Fig. 3 of the drawings, andtheir opposite ends are connected with the governor-arms S by means ofrods V. These rods are threaded at one end and provided with a Wing-nut,whereby the distance from the respective governor-arms and the free endsof the clamping-shoes may be increased or lessened. These clamping-shoesare designed to engage by frictional contact the sleeve on thechurn-cover.

It will thus be seen that as the clamping shoes are drawn against thesleeve the said shaft and operating mechanism will be retarded in itsmovement. It will also be seen that the clampingshoes may be so adjustedas to regulate the degree of clamping action, and hence the speed orrotary motion of the dasher. When the weight descends, the dasher willbe given a rotary motion through the medium of the intermediate gearing;but should the Weight descend too rapidly, so as to threaten injury toany ofthe parts, the centrifugal action or force will cause the Weightsor balls on the levers S to move outwardly, while, through the medium ofthe connecting-rod, the brake-shoes will be drawn against the sleevewith a force in accordance to the speed at which the machine is run, andthereby govern the fall of the weight and the consequent motion of thedasher.

The dasher-shaft may be provided with blades of any known or approvedconstruction.

Having described our invention, what-we claim is- 1. In achurn-operating mechanism, the combination of an upright frame, a weightarranged to travel thereon, a drum journaled therein, a rope connectingthe weight with the drum, gearing for rotating a dasher-shaft, and agovernor arranged upon the said shaft, whereby both the movements of theshaft and the falling of the weight may be controlled, substantially asspecified.

2. In a churn-operating mechanism, the combination of a verticalrotative shaft having a beveled gear at its upper end for rotating thesame, a governing device arranged upon the under side of the gear andconsisting of two pivoted brake-shoes, two pivoted weighted arms orlevers, and rods adjustably connect ing one end of each of therespective shoes with the respective weighted arms, whereby said shoesare adapted to bear upon a stationary collar to regulate the speed ofthe gearing, substantially as specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
